More specific objects and advantages of the invention will appear in the following description. 7 I V The invention consists in the novel construction, adaptation and combination of parts hereinafter described and claimed.

In the accompanying drawing,-

bodying my improvements shown appliedto the wall of a building, and in its extended or display relation; Fig. 2 is a side elevation of big. 1 with the building structurershown in section; Fig. 3 is a fragmentary front elevation of parts of the invention shown in Fig. 1 to a larger scale; and Fig. 4 is a vertical sec-- tion taken substantiallyv on the line 4-1 of Fig. 3.

rectangular curtain 5 of cloth or other suitable flexible material secured alongits upper edge to a roller 6. -This roller is of the self winding (Hartshorn) type, containing a spring, notshown, to effect rotation of the roller for winding the curtain thereabout in the direction in which it is represented in the drawing. Said roller is also provided with the usual controls, not shown, whereby the curtain may be stopped at a desired elevation.

Said curtain roller is rotatably mounted in brackets 7 secured to the ends of a-horizontal supporting bar 8 which, in turn, may be nailed or otherwise secured to a building wall9.

Intermediate its length the bar 8 has con- Y neoted thereto a vertical bar 10, hereinafter termed the post, whoselower end preferably bears upon the floor surface 11.

For convenience in packing for transporta- 1 tion and storage, the post 10 is made detach- Fi ure 1 is front elevation of devices eemable from the bar support 8 by the "provision in the latter of a post receivingsocket 12 between'two face plates 13. j The post 10 has marked thereon a scale 14 of numbers as 24, 25,"26, etc., locatedat distances in inches from its lower end, of the floor plane 11, designated by the respective numbers. The curtain hasmarked thereon a horizontal or height line 15 and a vertical'or centering line '16 crossing said horizontal line medially ofthe width of the curtain and. infront'of" the post 10 respectively. At theintersection" of said lines, however, thecurta'in is formed with a sight aperture 17 through which the scale numbers upon the post may be successively observed for regulating the curtain to have the height line 15 positioned at a selected the plane of the. floor, which positioning, would be indicated by the oorrespondingscale V elevation+say '34: inches,forexampleabovej 7 number, as 534, appearing at the'sight apertime 7 p i The curtain is provided, moreover, with V hor1zontal' scales 18 located in proximity 'to' the height line 15 and disposed symmetrically with respect to the centering line 16.

-The-divisions of the scales .18 are denoted by numbers as 16, 920, 24, etc'.,'which designate twice the distances, in inches, the respective scale marksare from said centering line. 19 represents a pair of rods, one rod ateach side of the curtain, the upper end of the rods being formed toprovide each with a hook 20 which is engageable over the upper part of the curtain which is wound upon the roller,

As best shown in Fig.4," a rod '19 is hung by'its hook to be in a planesubsta'ntially tangent to the front ofthe roll or wound-up portion of the curtain and thus,-when il1umi-'. V

' raised or lowered, as required to bring the height line at an elevationindicated by the scale 14above the floor which will correspond with the proper intersection of the light beams projected from the headlights of the car. With the curtain thus regulated, the height line 15 is utilized to indicate with respect tospots of light projected from the headlights whether or not'the headlights are suitably set to afford the requisite downward slant or inclination of the light beams.

If found by such a test tobe improper the same may be corrected-with reference -to the height lineby adjusting verticallythe headlights. j

The regulation of headlights horizontally is accomplished with reference to the rods 19 in conjunction with the res ective scales 18 against which shadows'of e' respective I rods are cast by the light beams from the headlights.

a vertically adjustable curtain having horizontally arranged scales thereon, devices provided in spaced relation in front of said zontal directional relations respectively of the headlights of an automobile, and means for.

supporting the curtain to retain the mark thereon at various elevations selectively.

In apparatus of the character described, the combination with a rotary roller, and a curtain connected to the roller to be rolled thereabout, said curtain having mark-' ings thereon, a rigid support for said roller, of 'means depending from said roller and adapted to indicatelthe disposition of light beams relative to said markings, said means being shiftable transversely of the curtain into selected positions with respect to, said markings. 7:
